SUPPLEMENTARY 25Feb2014:
The battery itself, I rate it with 2 stars! How So? Because I've fully charged the evening and the next day in the evening I am with the bike 5 km run with switched bicycle lamp. When I arrived at home I wanted to know how much juice is still inside (have a new charger which also indicates the charging status separately for each battery on a screen). And surprise: the Charger shows right at the beginning at each battery only 30%! Shortly thereafter, the level increased to 40%. Will also upload photos so.
I find that the batteries have discharged far too much for a 5km trip with a stink-normal 10 bicycle lantern; What are the 10-minute drive, 15? I was at least disappointed :(
